Astronomers from the University of Hawaiʻi have unexpectedly discovered an immense bubble of galaxies, named “Hoʻoleilana,” thought to be a fossil-like remnant from the birth of the universe.
An arrangement of galaxies in a giant bubble has been found not far from the Milky Way, and astronomers believe it could be a relic of the early Universe.
Astronomers have discovered the first "bubble of galaxies," an almost unimaginably huge cosmic structure thought to be a fossilised remnant from just after the Big Bang sitting in our galactic backyard.The bubbles then grew larger as the universe expanded, similar to other fossilised remnants from the time after the Big Bang.
